What's the best way no one knows you?

First, you think the worst is a broken heart
What's gonna kill you is the second part
And the third, is when your world splits down the middle
And fourth, you're gonna think that you fixed yourself
Fifth, you see her out with someone else
And the sixth, is when you admit 
That you may have fucked up a little.

And no...no there ain't no help, it's everyman for himself.
